I just bought myself a 61-key The Laboratory this last week, after visiting Arturia's website, expecting to have access to 4,300 sounds per its website advertisement. Instead, the CD came with "only" 3,500 sounds.

Dear Arturia or any Arturia users, is there someone to access these additional 800 sounds?

Update. IIRC, the 2.5.3 update released a few weeks ago, bumped everything in Laboratory up to the higher number. You should be able to tell, if you see the SEM, MiniV (used to be Modular V) and Wurlitzer Instruments. They were not in the earlier release. If you have those, i think you have the 4300 presets --
